Hi this is what I have used
if(get_field(‘cultivar’)){
$field_name = “cultivar”;
$field = get_field_object($field_name);
echo ‘‘, $field[‘label’],’‘ . ‘: ‘ . ‘<div class=”headlinename”>’, $field[‘value’],'</div>’,'</br>’;}
The code has a div wrapped round the value so you can use ::after content: ‘miles’; if you liked.
This piece of code only shows when there is a value too.
